MACHINE FOR'MAK'ING BARBS FOR od-Nose RINGS.

SPECIFICATION forming part of Letters Patent No. 382,693, dated May 15, 1888.

7 Application filed Sertcmber 2, 1887. Serial No. 248,648. (No modell To all whom it may concern.-

Be it known that we, JOHN H. DERINGTON and HIRAM J. PARKER, citizens of theUnited States, residing at-Springfield, in the county of 5 Greene and State of Missouri, have invented certain new and useful Improvements in Machines for Making Barbs for Hog-Nose Rings; and we do hereby declare the following to bea full, clear, and exact description of the invenro' tion,such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates toimprovements in machines for making barbs for hog-nose rings, the object of which is to provide a cheap, sim ple, and durable device for quickly cutting, punching, and forming barbs for hanging in the ring which is securedto hogs noses to prevent their rooting. tain by means of the mechanism illustrated in the accompanying drawings forming a part of this specification, in 'which i y 1 Figure 1 is a view in elevation of the entire machine from one of the back corners of the machine. Fig. 2 is a similar view fromthe opposite corner of the machine. Fig. 3is'a view of one of the barbs. Fig. 4 is a detail view in section of the feeding mechanism. Fig. 5 isa sectional view of the cutting and punching mechanism.

Similar letters of reference indicate corre sponding parts in the several figures;

A is an ordinary frame for supporting the machinery, which may be of any desired size and shape. B is a main lever having a fulcrum, b. Said lever operatesthe feedby an attached rod, 0, and drives the follower or plunger D for cutting and forming the barbs; Beyond the fulcrumof said lever is secured by a suitable hinge-joint a connecting-rod, E, for operating the lever L, which drives thepunch M. At one end of the said lever Bthe poweris sccured for driving the entire mechanism by working said lever back and forth, as indicated by the dotted lines. 7

D is a follower or plunger operated by the lever B, and having a die, G, secured to its fr'ont end by any suitable means. Said die is made to fit a-female die, H, which is made These. objects we atrounding at the frontedge, ligand has a square face at the back end, h, so that the projection v barb. Plunger Dis provided with guides 02 Q l d, which have set-screws d for. adj ustingthe same,v so that the dies will be properly adjusted to each other. 'Lis alever havinga fulcrum, Z,and ahinged connecting-rod, E, connecting it with .thelever B. (The attachment to lever B inay be at any desiredidistance from the fulcrum to regulate the stroke 'of the punch M. Said punch is secured tolever L, and works throughtherdies G H to punch the hole or eye i in the barb I whilethe points i i are being bent and the heel of the barb I being cut from theistripk Z Said dies have holes 9 and h for admitting the punch.

A O O are feed-rollersfor feeding the 'strip P Said past the dies for being cut into barbs. rollers are placed upon shafts o 0*,which have suitable bearings in springs Q Q for creating a "tension upon the strip'to force it forward into Said shafts are provided with the machine. cog-wheels R R,which engage each other, one

of the said shafts being provided with a ratcheti wheel, S, 'whichis operated by means'ofa ratchet-rod,l,which has a slot, 25, for engaging and driving the ratchet-wheel, said ratchetrod having a suitable spring for holding itin' place. One end of saidratchet-rod is hinged to one arm of a V-shaped motion-shifter,V. The other end of the said motion-shifter V is securedin the rod Ofor attaching the same to 0 lever B. For the purpose of regulating the length of the barb and to feed the strip at the proper time,th'e rod 0 is slotted, so as to give .a loss of motion while leverB isfoperating' the plungerand punch againstfthe'strip and [3095 feed the strip while the plunger and-punch I are being drawn back. Thisis accomplished by slotting. the rod 0 to receive one arm of the V -shaped motion-shifter, said arm being pro 7 vided with a pin, 0 which works in a slot, 4 I00 1 I I which is in the rod 0 at right angles to the slot 0, which receives the said arm. Thus the strip P is fed while the punch and dies are out of the way. Strip 1? passes through a suitable shield or tube,W,which is provided with slots 10 to admit the rollers O O, and has a spring, 10, at the end near the dies to hold thestripP firmly against die H to be cut. 01 is ascraper formed of a spring bent in any desired shape and secured to the plunger D for removing the barbs from the female die by pulling up on the points in case they should stick and cause them to drop.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

1. A frame, A, combined with levers B Ii, having a connecting-rod, E, and a punch and dies, substantially as shown and described.

2. A plunger,D,composed of a block hinged to lever B, placed in guides d d, provided with set-screws, said plunger having a projection, d spring-scraper d, and a die, G, substantially as shown and described.

3. The combination of levers B and L,having a connecting'rod, E, with plunger D, dies G H, and a punch, M, all substantially as and for the purpose specified.

- 4. The combination,with a frame, A, and levers B L,having a connecting-rod, E, of dies G H, plunger D, punch M, operating simultaneously with and through said dies, feed-rollers O O, operated by cog-wheelsR R,ratchet-wheel S, ratchet-rod T, V-shaped motion-shifter V, and rod 0, connected with lever B, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
